Vanished fish

I have a 55 gallon tank that I have had set up since early December. I have about 50# of lr, and a deep aragonite bed at one end getting shallower as it goes across the bottom (from about five inches at one end to about 1 inch at the other end). I cycled it very slowly, and my water has always tested very well. I got three hermit crabs, an emerald crab, and two turbo snails to keep it clean. Now I will get to my problem.
For my first fish, I bought a pair of engineer gobies. I know they get big and a lot of people don't like them, but they reminded me (especially the fully grown description) of the dragon goby in my freshwater tank. I also got a peppermint shrimp.
My peppermint shrimp disappeared within a few days, and was never seen again. One of the engineer gobies disappeared just a few days after that. I don't know about the peppermint shrimp. As far as the goby, I had to pull my rocks out at one point to find a sea hare that had been in there, so they are unfortunately on top of the substrate (at the shallow end), so I suspect it dug under one that shifted and squished him.
The other goby is doing just fine, except for being a scaredy fish and never going far from his den.
I left the tank alone for a while to make sure that any waste produced by rotting dead fish would have time to dissipate. I have checked the water, it has been fine since then.
Yesterday I bought two new fish; a flame hawk and a percula clown. The clown seemed fine at the store - he ate and everything, but didn't seem toi energetic. He was in a tank with a tang that was harassing him a bit, so we chalked his lack of energy up the tang. I think it is important to state that he was still swimming around and ate a bit when fed, he just wasn't as energetic as ones in other tanks. We bought him mostly because we felt bad for him getting picked on, and thought we would be doing him a favor.
Last night he was doing fine.
This morning when I woke up, he was gone. Simply gone. I haven't taken the rocks out, but I've looked at them from all angles, and can not see him ANYWHERE. The hermit crabs and emerald crabs aren't acting funny, either (like hiding in one spot eating a fish).
Do you think he swam into some of the gobies burrows and vanished?
My tank isn't completely covered - could he jump out of it? The water is about an inch and a half from the top, with a slight overhang. The gap is only about two inches wide. Can clowns jump like that? I haven't read they could, but who knows. If he did jump out, one of the cats probably could have gotten him. (the cats can't get on top of the tank, though).
Do you think he burrowed down into the sand bed, or into some tonga rock in the one place you can't see him?
Any help would be appreciated. I know this sounds like one of those "a man is hanging alone in a room with no one around and a puddle on the floor" things, sorry.

hmm..
usually if a fish is scared, sick or dying, it goes somewhere where no predators can see them vulnerable so its very likely that something happened to your fish. I myself have had TWO fish 1goby 1blenny jump out of my tank bcuz of a 6inch opening i had unsecured in my tank just a few days apart (fix that problem real quick!). there is a possibility something could of startled him and he could of jumped out, but you would smell/and or see the body in less u have a cat or dog? lol
how often do u do water changes? how often do you test ur water?
 
wow that is simply crazy... he could be trying out a new cave.. one time i thought that my blue hippo disapeared and i found her hiding in a little cave in one of the rocks.. but i doubt your hermits grabbed him and took a chunk out of him.. im sure they would only start to devour if they had found the fish lying on the ground.. i have a saddleback clown and hermits also.. but nothing in that nature has ever happened..

I do have two cats, who could get to the back of tank right now if it jumped out back there.
I do water changes about every two weeks, and test my water about every week or two. Probably test about every ten days.

Mantis Shrimp? Do you here any clicking coming from the tank at night?

No, I don't think so. Plus the tank is very new, and those take a while to develop, don't they?
I think that it did jump out and fall prey to my cats, because now my cats have been patrolling behind it and my other tank, like they're looking for some more.
